Answer : The mass of lead in 139 g of is, 86.9 grams.
Explanation : Given,
Mass of = 139 g
Molar mass of = 331.2 g/mol
Molar mass of Pb = 207.2 g/mol
Now we have to calculate the mass of lead.
As, 331.2 g of has 207.2 g of lead
So, 139 g of has of lead
Thus, the mass of lead in 139 g of is, 86.9 grams.
Answer:
The concept of lewis acids and bases can explain the acidic nature of CO2. A lewis acid is a compound which can accept an electron pair whereas a lewis base is a compound which can donate an electron pair. CO2 acts as a lewis acid.
For example, water. In its liquid state we drink it , in its solid state (ice ) we use it to make our drinks colder or t numbs pain when wrapped in cloth and it’s gas state ( water vapour) we steam vegetables. In conclusion many different properties of matter are used for various purposes
